If they treat Bin Laden and he then plans a really dramatic terrorist attack on us, they are not better than us.
I am using an extreme example to make a point.
Healing someone in poor working conditions does not, by itself, make someone better than us. Well-meaning, hard-working idealists often do more harm than good.
I think I have to lean toward the point that sweneop is making. I think that healing people is a noble calling with very few exceptions -- whether it's done by MSF, or U. S. Army reconstruction teams, or anyone else.
If MSF feels Afghanistan is too dangerous, that's their choice and I've got to respect the good work they've done there in the past. I just hope they'll put their resources to good use elsewhere. And I hope U. S. organizations (like the U. S. military) will fill the void as best they can in Afghanistan.
